Officials in Afghanistan say the number of Islamic State fighters killed by a US bomb has increased to 90.

It was the largest conventional bomb ever used by America's military in combat.

It targeted caves in the east of the country which, according to army chiefs, were being used as a 'sanctuary' for militants.

The Pentagon has released footage of the bomb posting a video of the strike on Twitter, under the tag MOAB or 'Mother of All Bombs'.
